This module exploits an arbitrary file upload in the sample PHP upload handler for blueimp's jQuery File Upload widget in versions <= 9.22.0. Due to a default configuration in Apache 2.3.9+, the widget's .htaccess file may be disabled, enabling exploitation of this vulnerability. This vulnerability has been exploited in the wild since at least 2015 and was publicly disclosed to the vendor in 2018. It has been present since the .htaccess change in Apache 2.3.9. This module provides a generic exploit against the jQuery widget.

The version of jQuery-File-Upload running on the remote host is affected by an arbitrary file upload vulnerability. An unauthenticated attacker could leverage this vulnerability to gain access to the host in the context of the web application user.
